SACRAMENTO, Calif. — November 11, 2026. California voters have rejected Proposition 40, a proposed one-time tax on the net worth of the state’s billionaires, according to projections by the Associated Press and CBS News. The outcome follows a campaign marked by enormous financial contributions, divisions among Democratic leaders and competing arguments about how to pay for public healthcare.
Returns reported by KQED using Associated Press data showed approximately 52.5% voting no and 47.4% voting yes, with about 89% of the estimated vote counted. The AP called the measure defeated on November 9. These are reported results, not the state’s final certified count; California’s Secretary of State has scheduled certification for December 11, 2026.
What Proposition 40 Would Have Taxed
The measure would have imposed a one-time 5% tax on the net worth of people who were California residents on January 1, 2026, and whose covered assets exceeded $1 billion. The tax would have been due in 2027, with an option to make payments over five years at additional cost. Business ownership, securities and other financial holdings would have been included; real estate and certain pension and retirement assets generally would have been excluded.
Unlike a tax on wages or realized investment gains, a wealth tax targets the value of accumulated assets after accounting for liabilities. The state’s official legislative analysis described the proposal as a temporary revenue source rather than a recurring annual tax.
Proposition 40 earmarked 90% of its proceeds for public healthcare services and the remaining 10% for education, food assistance and administration. Its main sponsor, SEIU-United Healthcare Workers West, said the money could help offset federal healthcare funding cuts. The union and other supporters estimated roughly $100 billion in revenue, but California’s nonpartisan legislative analyst gave a more cautious projection of tens of billions of dollars over several years and warned that the amount was difficult to predict.
Why the Campaign Divided Political Allies
Supporters included the California Democratic Party, Sen. Bernie Sanders and healthcare workers’ unions. They argued that taxing some of the state’s largest fortunes could help sustain hospitals, clinics and Medi-Cal while addressing the gap between investment wealth and taxable income.
Opponents included Gov. Gavin Newsom and organizations such as the California Teachers Association and Planned Parenthood affiliates. They contended that a state-only wealth tax could encourage affluent residents to relocate, potentially reducing future income-tax collections. They also questioned whether a one-time revenue stream could address ongoing healthcare costs.
California’s legislative analyst estimated that behavioral responses to the tax, including possible relocations, could reduce annual income-tax collections by less than $1 billion. That estimate was a forecast with uncertainties, not proof that the projected departure or losses had already occurred.
Hundreds of Millions of Dollars in Campaign Money
One of the election’s defining features was the scale of opposition fundraising. CalMatters reported that wealthy opponents collectively contributed approximately $378.4 million to efforts against the billionaire tax and related ballot campaigns, compared with approximately $33.5 million raised by supporters of Proposition 40. Google co-founder Sergey Brin was reported to have given more than $100 million to the opposition group Building a Better California.
Those financial totals describe campaign fundraising as reported by CalMatters, including activity related to competing measures; they should not be mistaken for the narrower amount spent exclusively on ads against Proposition 40. The election result alone does not establish that campaign spending caused voters’ decisions.
Two Other Propositions Complicated the Vote
California also voted on Propositions 41 and 42, competing measures designed to constrain certain state taxes. Proposition 41, which sought additional oversight of special taxes, was rejected according to CBS News. Proposition 42, which would restrict taxes on ownership of financial assets and many retroactive taxes, was leading in preliminary returns reported by KQED on November 10. Final certification of the election remains pending.
Because Proposition 40 was itself defeated, it will not take effect regardless of the final tally on the competing measures. Proposition 42’s eventual outcome could still shape future attempts to pass similar taxes.
What Comes Next for California
The rejection does not itself change healthcare benefits or reduce existing program funding. It does mean lawmakers cannot rely on the proposed one-time tax to raise additional revenue. Supporters have said they may return with another proposal in 2028, while opponents favor different approaches to long-term fiscal planning.
The underlying policy dispute remains: whether major healthcare funding gaps should be addressed through changes in taxation, spending, federal policy or a combination of measures. For now, the election result settles Proposition 40, not that larger question.
